Cordierite DPF
This product is a kind of special structure and special material of wall flow ceramic honeycomb ceramic filter element, used in the diesel engine exhaust gas purification device, using the hole wall of the pore wall flow filter body, intercept, capture the carbon in the diesel exhaust smoke particles, diesel exhaust gas purification. There are cordierite and silicon carbide material.
- Benefits of Products:
- High porosity of hole on the wall of high porosity, good liquidity and uniform distribution
- High temperature resistance, chemical corrosion resistance, thermal shock resistance and thermal shock resistance is strong
- The pressure drop is small
- High filtration efficiency, able to adapt to all kinds of regeneration
- Low thermal expansion coefficient
